Description

System with food processor and household mixing device

Technical Field

The invention relates to a domestic system comprising a food processor and a mixing device. The invention also relates to a holder part for a mixing device.

Background

A food processor with a container is known from publication EP1639928a 1. The container includes a set of knives. The food processor may chop, grind, or simply mix the food ingredients in the container. In order to be able to chop the food material, the set of knives must be able to rotate in the direction of their sharp edges with a high rotational speed and a high torque. The electric drive of such a food processor is selected to have a corresponding power.

A beater for a food processor with a permanent magnet synchronous motor is known from publication CH702302a 2. The permanent magnet synchronous motor includes a plurality of permanent magnets arranged at regular intervals around the circumference of a rotor of the motor.

Instruction manual "VORWERK INTERNATIONAL STRRECKER&Co. company thermmix 6, 02/19 "is known, which discloses a food processor with a removable container. There are a plurality of accessories for the container, such as cooking inserts,

the container is a container, and the container is a container,

a plug-in base, a mixing accessory, so that many different foods can be prepared.

If the food processor can perform a variety of operations, such as mixing, chopping, and heating, the food can be used to prepare a variety of different foods. Particularly for multi-function food processors, there is therefore a need for having more than one container. If the food is prepared in the first container, the second container can be used to prepare a second food in parallel without transferring or cleaning the containers therebetween.

A mixing device comprising a container and a mixing tool is known from the publication DE102009016897a 1. The mixing tool is integrated into the upper part of the container. The upper part comprises a piezoelectric stepping motor as a driver. The piezoelectric stepping motor is relatively small and light.

When preparing one or more foods, it is often desirable to mix a first material and to chop and/or mix a second material. If only one food processor is provided, these steps must be performed in succession. This problem can be solved by providing a second food processor. However, it is not very practical to provide a second food processor to solve this problem, as the full potential of such food processors is not developed at the same time and is also rare.

The present invention aims to simplify and accelerate the preparation of food with reasonable technical effort.

Disclosure of Invention

In order to solve this problem, a system having the features of the first claim and a holder part for a mixing device having the features of the further claims are provided. Advantageous embodiments follow from the dependent claims.

The present invention includes a system comprising a frame member of a food processor and a frame member of a mixing device and at least one container having a mixing tool located therein. The container can be used as a component of a food processor as well as a component of a mixing device. This means that the container can be inserted into a holder part of the food processor and then become an initial part of the food processor. However, it is also possible to remove the container from the holder part of the food processor and insert it into the holder part of the mixing device. The container then becomes a component of the mixing device. Thus, it is possible, depending on requirements, to use the container first as a component of a food processor and thereafter as a component of a mixing device, and vice versa, even during the preparation of food. If the same ingredients are to be processed, there is no need to transfer the ingredients from the container of the food processor to the container of the mixing device and vice versa.

The food processor is advantageously configured such that the mixing tool can be rotated by the food processor at a higher rpm than the maximum rpm possible with the mixing device. Since the mixing device in this embodiment does not require a large motor due to the low rpm, the housing parts of the mixing device can be constructed particularly small compared to the housing parts of the food processor. Thus, the space required by the housing parts of the mixing device is small in addition to the space required by the food processor.

The maximum possible rotational speed at which the food processor is able to rotate the mixing tool is preferably at least five times or more greater than the maximum possible rotational speed at which the mixing device is able to rotate the mixing tool. For example, if the mixing device is capable of rotating the mixing tool at a speed of at most 1,000 revolutions per minute, the food processor is capable of rotating the mixing tool at a speed of at least 5,000 revolutions per minute.

A holder part refers to a part of a mixing device or a food processor intended to be placed on a base, such as a table. The carrier part can thus have, for example, projections on its underside. In the seated state, the projection is in contact with the base. The protruding members may be made of an elastomer to achieve a non-slip seating of the bracket parts and to reduce vibrations.

Preferably, the maximum possible rotational speed at which the food processor is capable of rotating the mixing tool is at least ten times, or even at least twenty times or more, greater than the maximum possible rotational speed at which the mixing device is capable of rotating the mixing tool.

In order to be able to make the installation space for the holder part of the mixing device particularly small, it is preferred that the mixing device is designed such that the maximum possible rotational speed of the mixing tool is 1,000 revolutions per minute, at which the mixing device can rotate the mixing tool. If this rpm is not exceeded, a stepper motor may be used as a driver, for example. The shaft of the stepper motor can typically rotate at 1,000 revolutions per minute without its torque being too low for the application. In this embodiment no gearbox is required. Advantageously, the overall height of the mixing device can also be kept small. This results in a low center of gravity, which is particularly important for a mixing device that operates without malfunctions, because the frame parts of the mixing device are relatively small and therefore relatively light compared to the frame parts of the food processor.

Preferably, the mixing device is capable of rotating the mixing tool at a maximum possible speed of rotation not exceeding 400 revolutions per minute. With regard to the usual constructional height of the container used in the food processor, it is not necessary to close the container of the mixing device (which may also be the container of the food processor) tightly with a lid, so that no food material can be ejected from the container. Thus, the locking mechanism for the lid may be omitted in the mixing device. The lid may then be removed from the container of the mixing device at any time, for example by lifting the lid. This means that the locking mechanism does not have to be unlocked first before the lid can be removed.

The container is typically constructed to a height of between 10cm and 30 cm. If the distance between the upper edge of the container and the bottom of the container is at least 10cm, this is usually sufficient to ensure that no food ingredients are ejected as a result of rotating the beater tool at a rotation speed of not more than 400 revolutions per minute. Preferably, the distance between the upper edge of the container and the bottom of the container is at least 15 cm.

If the container is standing on a foundation, the bottom of the container may be at a distance from the foundation. The total height of the container is then greater than the distance between the upper edge of the container and the bottom of the container. This embodiment allows, for example, to provide electrical contacts below the bottom of the container. The electrical contacts may be connected to the sensor of the container. The sensor may be a temperature sensor capable of measuring the temperature of the container. The electrical contacts may be connected to the heating means of the container. The electrical current may then be conducted via the electrical contacts to the heating device to heat the container.

By means of a locking mechanism in the sense of the present invention, the lid can be locked when it closes the container. The lid cannot then be removed from the container. This may additionally help to keep the installation space for the housing parts of the mixing device small if no such locking mechanism is present in the mixing device because it is not required. This is particularly true in comparison to the case where the food processor includes a motor-driven locking mechanism for the lid. Motor-driven locking mechanisms require a particularly large installation space. The possibility of omitting the same locking mechanism in the mixing device saves a particularly large amount of space in the holder part of the mixing device.

Preferably, the food processor comprises a motor driven locking mechanism for the lid of the container. A motor-driven locking mechanism is advantageous in order to be able to prepare the food in an at least partially automated manner. The locking and unlocking can then be effected in an automated manner by the controller of the food processor. This embodiment of the invention is particularly advantageous if a motor-driven locking mechanism is provided as locking mechanism in the case of a food processor, and if no locking mechanism is present in the lid for the container in the mixing device.

The lid may have an opening. Then, when the lid otherwise closes the container, an ingredient, such as a fragrance, can be introduced into the container through the opening. When the diameter of the lid is 15cm to 25cm, the diameter of the opening may be, for example, 1cm to 8 cm.

In particular, the mixing device enables a maximum possible rotation speed of the mixing tool not exceeding 220 revolutions per minute. This may ensure that the food ingredients are almost never thrown upwards during mixing. The upwardly thrown material may then adhere to the inner wall of the container without participating in the mixing process. This problem is avoided by limiting the number of revolutions to 220 revolutions per minute. A higher number of revolutions is not necessary, since the food processor can be used for a higher number of revolutions. It has also been found that for parallel food preparation, it is rarely necessary to use two different parts of the apparatus to simultaneously rotate at more than 220 revolutions per minute. This finding is another reason why it is particularly advantageous to limit the maximum possible rotational speed to 220 revolutions per minute.

Preferably, the food processor is capable of rotating the mixing tool at a maximum possible rotational speed of at least 5,000 revolutions per minute, particularly preferably at least 8,000 revolutions per minute, in order to be able to not only mix but also chop. Preferably, the maximum possible rotational speed at which the food processor is able to rotate the mixing tool does not exceed 16,000 revolutions per minute, particularly preferably does not exceed 13,000 revolutions per minute, since the technical effort would be too high compared to the yield.

In one embodiment of the invention, the rpm of the rotational speed of the food processor and/or the mixing device may be continuously adjusted. Thus, if the maximum possible rotational speed is 200 revolutions per minute in the case of a mixing device, this rotational speed can be continuously reduced to zero. If the maximum possible rotational speed is 12,000 revolutions per minute in the case of a food processor, this rotational speed can be reduced continuously to zero, for example.

Preferably, however, the rpm of the rotational speed of the food processor and/or the mixing device can only be adjusted in a stepwise manner. In this way the operation can be kept simple. Operational errors can be reduced. It is also not necessary to be able to continuously adjust the rotational speed for preparing the food.

In order to make it particularly easy to operate the mixing device without fear of operating errors, it is preferably possible to set a maximum of three, preferably a maximum of two different rotational speeds for the mixing device. For example, in one embodiment of the invention, the first step is between 80 and 120 revolutions per minute and the second step is between 180 and 220 revolutions per minute.

Preferably, the rotational speeds in the food processor and the mixing device have the same step. For example, if a step 1 is to be used for mixing according to the recipe, it is not important which device is referred to in this description if a step 1 in the food processor corresponds to a step 1 in the mixing device in this embodiment. Thus, if the number of revolutions of step 1 in the mixing device is between 80 and 120 revolutions per minute, the number of revolutions of step 1 in the food processor is also between 80 and 120 revolutions per minute. If there is a step 2 of between 180 and 220 revolutions per minute in the mixing device, there is also a step 2 of between 180 and 220 revolutions per minute in the food processor. The same step of the rotational speed does not mean that the rotational speeds of step 1 or step 2 must be exactly the same. In practice, small differences of, for example, a maximum of 20% are not detrimental to the preparation of food. In general, the difference is even preferred, for example to achieve acoustic advantages. For example, resonance frequencies can thereby be avoided. These may be different because the food processor and mixing device are configured differently. For this reason, for example, the food processor can mix at 100 revolutions per minute in step 1, while the mixing device mixes only at 80 revolutions per minute in step 1, for example to achieve an acoustic advantage.

The control for the rotational speed and the drive for the mixing tool are located in the respective carrier part. The holder part of the mixing device can be constructed such that it can only be rotated in

steps

1 and 2. The holder part of the mixing device can be constructed such that it can only be rotated in

steps

1, 2 and 3. The holder part of the mixing device can be configured to rotate with only step 1, with only step 2 or with only step 3. The frame part of the food processor may be constructed such that it can be rotated in

steps

1, 2, 3, 4, etc.

The lowest rotation speed of step 1 should be at least 50 revolutions per minute, since lower rotation speeds are used too little.

In principle, the number of steps of the rotational speed is greater in the case of a food processor than in the case of a mixing device. Preferably, the number of steps in the case of a food processor is at least twice, particularly preferably at least three times, greater than this. Thus, if there are two steps of the rotational speed in the case of a mixing device, for example step 1 and step 2 described above, there are at least four steps of the rotational speed in the case of a food processor, in particular at least six steps of the rotational speed.

Preferably, the lowest step, i.e. the step of the lowest rotational speed, is the same for the food processor and the mixing device in the above sense. The previously described step 1 may be the lowest step, i.e. the step with the lowest rotational speed. Both the mixing device and the food processor can be operated in step 1. For both devices, a lower rotational speed than zero is not possible.

In food processors, therefore, there are generally more than three steps of the rotational speed, for example at least eight steps, particularly preferably at least 10 steps. However, subdivision into about 40 steps is not usually provided, as in practice even more precise subdivision is not required. If there are identical steps in the rotational speed in the food processor and the mixing device, the food processor in particular also comprises steps for the rotational speed, for which the mixing device is not present. This is especially true if the holder part of the food processor can be rotated at a higher rotational speed than the holder part of the mixing device. In the food processor, one or more further steps are then present which are not present in the mixing device, so that the mixing tool can be rotated at a correspondingly higher rotational speed by means of these further steps. However, one or more further steps in the food processor may also be such that the mixing tool may be rotated at a lower rotational speed. The food processor may rotate the mixing tool at a lower speed than the mixing device.

For example, in the case of a food processor, the rotational speed may be increased exponentially in steps. In the case of food processors, only stepwise linear increases have not proven effective in preparing food in practice. For example, it may be rotated at a rotational speed of 80 to 120 revolutions per minute in step 1, at a rotational speed of 180 to 220 revolutions per minute in step 2, at a rotational speed of 470 to 530 revolutions per minute in step 3, and at a rotational speed of 10,000 to 12,000 revolutions per minute in the last step.

In one embodiment, the mixing tool is equipped with a pressure safety device. In this embodiment, there is a threshold value of the torque that the mixing tool can transfer from its drive to the food ingredients. If the threshold value of the torque is exceeded at least for a predetermined period of time, the pressure safety device has the effect that the shaft of the drive can be rotated without the mixing tool rotating at the same speed. For example, if the rotation of the mixing tool is blocked for, for example, 5 seconds, the effect of the pressure safety device is that after the lapse of 5 seconds the shaft of the drive can rotate, but without the mixing tool also rotating. In this way, damage to the drive of the food processor and/or the drive of the mixing device is avoided if the mixing tool is blocked. The pressure safety device may be a burst safety device. Thus, the pressure safety device may have a predetermined rupture point that ruptures when a threshold value of torque is exceeded for a predetermined period of time. After the predetermined breaking point has broken, there is then no rotationally fixed connection, for example, between the shaft of the mixing tool and the tool of the mixing tool. If the shaft of the mixing tool is subsequently driven, it can be made to rotate independently of the mixing tool.

Preferably, for safety reasons, even if the mixing tool comprises a pressure safety device, the carrier part of the mixing device has a control for limiting the torque of its drive. The controller limits the power of the electric drive to a maximum value. For example, the controller may be configured such that it maintains a constant rpm of the mixing tool by adjusting the amperage of the electric drive, but limits the maximum possible amperage to, for example, 0.8A or 1A. The maximum current value and thus the maximum torque value are usually chosen such that the mixing device mixes the food ingredients only with a smaller torque than the torque with which the food ingredients can be processed in the case of a food processor. It is to be considered that for mixing, only a small torque is usually used to prepare the food. For example, the maximum possible torque may be 0.5N · m.

Preferably, the holder part of the mixing device is provided with a cutting device. The shut-off device shuts off the power supply of the electric drive in an automated manner when the above-mentioned maximum value of the current intensity or torque is reached or at least reached within a predetermined period of time. The time period may be, for example, 2 to 10 seconds, such as 5 seconds. Then, if the above-mentioned maximum value is reached for five seconds, the shut-off device cuts off the power supply to the electric drive in an automated manner.

Preferably, for safety reasons, the shut-off device then shuts off not only the power supply to the electric drive in an automated manner, but also to other electrical consumers.

The further consumer can be an electrical heating device of the mixing device, by means of which the container can be heated. The container may then comprise heating means and electrical contacts. The cradle member of the mixing device may then comprise corresponding electrical contacts. If the container is inserted into the holder part of the mixing device, the electrical contacts of the mixing device are connected to the electrical contacts of the container. The heating means may then be supplied with current from the support member of the mixing device, thereby heating the container.

The holder part of the food processor may also have the same electrical contacts in order to be able to heat the container.

If the mixing tool has a pressure safety device, the maximum value of the power limit is chosen so small that it cannot trigger the pressure safety device. It is considered that it should be possible to provide higher torques for preparing food, for example for kneading dough using a food processor. However, due to its power limitation, the mixing device is not suitable for kneading dough.

In order to satisfy the safety requirements particularly well, the torque that can be applied by the mixing device by means of its mixing tools is a maximum of 1N · m, preferably a maximum of 0.5N · m. Particularly preferably, the maximum torque is not more than 0.4N · m, so that the mixing device can be operated even without a lid without any safety hazard. Then during the course of operation, the container of the mixing device is open.

In order to be able to mix with sufficiently high force, the control for limiting the torque is provided such that the torque of the mixing tool can be at least 0.1N · m, preferably at least 0.2N · m, particularly preferably at least 0.3N · m. This ensures that the common food ingredients can be mixed by the mixing device with the required force.

In one embodiment of the invention, the torque of the mixing tool of the food processor may be greater than 2N · m, for example at least 2.5N · m or 3N · m. Such a torque allows for example kneading dough.

Preferably, in particular, the footprint of the housing part of the mixing device is smaller than the footprint of the housing part of the food processor. In kitchens, it is particularly important that the footprint required to house the kitchen appliances be kept small. It is therefore particularly advantageous if the footprint of the housing parts of the mixing device is small compared to the footprint of the housing parts of the food processor.

The footprint refers to the area required to place a support member of a food processor or a support member of a mixing device on a base, such as a countertop in a kitchen.

The length and width of the footprint of the frame part of the mixing device, as seen in a top view of the container and/or the mixing device, is preferably hardly greater, particularly preferably not greater, than the maximum length and maximum width of the container. For the reasons mentioned above, a second container is generally required anyway to operate the food processor. In particular in these cases, the housing parts of the mixing device do not require any additional space in practice.

The length and width of the footprint of the frame part of the mixing device preferably correspond to the maximum length and width of the container. On the one hand, this minimizes the additional space required for the housing parts of the mixing device. On the other hand, the footprint is maximized, so that sufficient stability can be achieved for the mixing device during operation.

The footprint of the housing part of the mixing device may be at most 35cm long to keep the space requirements low. The footprint of the housing parts of the mixing device may be at most 25cm wide to keep the space requirements low. In order to achieve sufficient stability, the footprint of the housing parts of the mixing device should be at least 20cm long. The footprint of the housing parts of the mixing device should be at least 15cm wide to achieve sufficient stability.

In practice, one vessel is sufficient for the operation of the system. In practice, however, there are usually already two containers and it is simply possible to prepare a plurality of foods in parallel with the food processor without much effort. A second footprint must be provided for the second container. If the second container can be inserted not only into the housing part of the food processor but also into the housing part of the mixing device, the presence of the mixing device has in any case in a practical sense no effect of increasing the required footprint.

In one embodiment, the mixing device has a construction height that is less than the construction height of the food processor. The low construction height is particularly advantageous since the console part of the mixing device has a relatively small footprint, since it allows a particularly low center of gravity. The low center of gravity contributes to stability and thus to trouble-free operation.

In particular, the distance of the upper edge of the container to the bottom surface of the mixing device is smaller in the case of the mixing device than in the case where the container is a component of a food processor. In the case of a mixing device, this also contributes to a relatively low center of gravity.

In one embodiment, the system includes a second container configured similarly to the container described above. For example, if the food is first prepared in the first-mentioned container by means of a food processor and then this container is used in a mixing device as described above, a second container can be used for the parallel preparation of another food by means of a food processor.

Preferably, the holder part of the food processor is constructed such that the direction of rotation of the mixing tool can be changed. Thus, the food processor may be used in an improved way for pure mixing and alternatively for mixing and chopping food ingredients.

The housing part of the mixing device and/or the housing part of the food processor may comprise an electronic controller. If present, the operation of the food processor and/or the operation of the mixing device may be controlled by the controller.

Preferably, the housing part of the mixing device and the housing part of the food processor are constructed such that they can wirelessly exchange data with each other. The data exchange can be used to control the coordinated operation of the mixing device or the food processor by means of the controller. Wireless exchange between the cradle members is possible, e.g. via

The food processor and/or the mixing device can have a heating device as a device for preparing food, with which the container can be heated. The housing part of the food processor and/or the housing part of the mixing device may comprise a controller by means of which the heating of the container can be controlled. The heating device may include an electric resistance heater capable of generating heat. The heating device may comprise a temperature sensor capable of detecting, displaying and/or controlling the temperature. The controller may allow the container to reach a selected temperature and be maintained at that temperature. The housing parts of the food processor and/or the housing parts of the mixing device can be constructed such that the temperature can be selected and adjusted continuously.

The housing parts of the food processor and/or the housing parts of the mixing device can be constructed such that the temperature can only be selected and set in a stepwise manner. This embodiment is preferred in order to keep the operation simple and avoid operation errors. For example, the temperature may be set in 5 ℃ steps, for example starting with a temperature of 25 ℃ or 30 ℃. Preferably, the lowest temperature that can be set at the housing part of the food processor and the housing part of the mixing device is the same. For example, the minimum temperature that can be set at both rack components can be 25 ℃ or 30 ℃. The step size of the two carrier parts is preferably the same if the temperature of the two carrier parts can only be changed in a stepwise manner. Thus, if the temperature can be varied in 5 ℃ steps in the case of a food processor, the temperature can also be varied in 5 ℃ steps only in the case of a mixing device. This consistency ensures that the temperature can be set in the same way in both devices. This facilitates parallel preparation of food according to the recipe.

Preferably, the maximum temperature that can be set for the housing part of the mixing device is lower than the maximum temperature that can be set for the housing part of the food processor. Since the container is generally less protected in the case of a mixing device, it is advantageous for safety reasons if the maximum temperature of the mixing device is lower than the maximum temperature of the food processor.

Preferably, the container comprises an electrical resistance heater as a component of the heating means. This reduces technical effort if heating means are to be provided for both the food processor and the mixing device. Preferably, the container comprises a temperature sensor to detect, display and/or control the temperature.

As a device for preparing food, the food processor and/or the mixing device can be provided with a balance with which the raw materials or food introduced into the container can be weighed. The food processor and/or the mixing device may comprise a controller with which the balance and thus the weighing can be controlled. Preferably, only the food processor comprises a balance and an associated control, in order to be able to keep the installation space of the mixing device particularly small.

As a device for preparing food, the food processor and/or the mixing device can be provided with an optical sensor with which the raw material introduced into the container can be monitored optically. The container may include an optical sensor. The food processor and/or the mixing device may comprise a controller by means of which the optical sensor and thus the optical monitoring may be controlled. The optical sensor and the controller may be present only at the housing part of the food processor, so that the installation space of the mixing device is kept particularly small.

The invention also relates to a support element of the mixing device of the system. Thus, the bracket component may be a component of the system. The support element of the mixing device may be designed as described previously.

The holder part of the mixing device may have a recess which may be adapted to receive the lower part of the container. The shape and diameter of the recess may correspond to the shape and diameter of the lower part of the container in order to hold the container firmly and reliably in the desired position by means of the bracket member. The height of the lower portion may be no more than 30%, preferably no more than 25% of the total height of the container. For example, if the container is 20cm high, the height of the lower portion may be limited to 20:3cm or 20:4 cm. The height of the lower portion may also be no greater than 35% of the overall height of the container.

The holder part of the mixing device comprises an electric drive by means of which the mixing tool located in the container can be driven. The electric drive may comprise a stepper motor. The stepper motor is particularly suitable for use in a mixing device, since only the mixing tool is rotated at a low rpm compared to the rotational speed of the food processor. Thus, the mixing tool can be directly connected to the shaft of the stepper motor. Thus, the installation space can be small, so that the additional space required for the bracket parts of the mixing device can be small.

Preferably, the electric drive of the mixing device is a hybrid stepper motor. The hybrid stepper motor can only rotate at relatively low rpm. Since the mixing device is only intended to take on the mixing task as a complement, only a low rpm is even advantageous for safety reasons.

Hybrid stepper motors have also proven suitable because their torque is low relative to their weight, which is also advantageous for safety reasons. Another advantage is that the torque does not or hardly depend on the rpm in the relevant rpm range. Thus, the torque of a commercially available hybrid stepper motor is in a practical manner constant or at least constant in the rpm range of 50 to 500 revolutions. An rpm of from 50 to 500 revolutions is sufficient for the present application. The torque may then be, for example, at least 0.2N · m or 0.3N · m and/or not more than 0.4N · m. For example, the torque may be 0.35N · m.

Hybrid stepper motors are relatively heavy, especially compared to piezoelectric stepper motors. Since the electric drive is accommodated in the carrier part of the mixing device, the hybrid stepper motor contributes to the relatively high weight of the carrier part. The relatively high weight of the bracket parts of the mixing device is advantageous for providing stability during operation. However, the housing parts of the mixing device may be small compared to the housing parts of the food processor. This can avoid the problem of excessive space in the home.

The electric drive is usually located below the container when the container is inserted into the holder part of the mixing device and when the holder part is arranged as desired.

The electric drive may comprise a plurality of permanent magnets. Preferably, however, the electric drive comprises a rotor with only one permanent magnet. Thus, the assembly effort can be kept particularly low.

Preferably, the electric drive comprises a stator having a ring shape and a rotor within the ring shape. This design is particularly suitable for connecting the shaft of an electric drive to a mixing tool.

Preferably, the segments with teeth project inwardly from the ring. A coil is wound around each segment. The rotor includes outwardly projecting magnetic pole teeth.

Preferably, the teeth of the stator may be directly opposite the teeth of the rotor. At the same time, other teeth of the stator may be offset from other teeth of the rotor.

Preferably, the rotor comprises a first tooth and a second tooth. The first tooth is a magnetic north pole or is traversed by a first magnetic flux of the magnet. The second tooth is a magnetic south pole or is traversed by a second magnetic flux of the magnet in a direction opposite to the first magnetic flux. Thus, the first tooth may be formed by the north pole of the permanent magnet. The second tooth may be formed by a south pole of the permanent magnet. However, the magnet may also be adjacent to the first and second teeth such that the magnetic flux generated by the magnet passes through the first and second teeth. Then, the magnetic flux through the first tooth extends opposite to the magnetic flux through the second tooth. For example, the first tooth then acts as a magnetic north pole. The second tooth acts as a magnetic south pole. In the sense of the invention, the first tooth and the second tooth are then magnetically polarized.

The first and second teeth generally form an outer periphery of the rotor. The first tooth is typically located between two second teeth and vice versa.

Preferably, the rotor comprises a first rotating body made of ferromagnetic material provided with a first tooth. Preferably, the rotor comprises a second rotating body made of ferromagnetic material provided with second teeth. The north pole of the permanent magnet preferably extends into the first rotation body. The south pole of the permanent magnet preferably extends into the second rotational body.

The teeth of the rotor are preferably curved outwards on their upper side. The teeth of the stator are preferably curved inwards on their upper side.

Preferably, the mixing tool comprises a blunt edge and an opposite sharp edge. The mixing device is constructed such that the mixing tool can only be rotated in the direction of the blunt edge. By configuring the mixing device such that the mixing tool can only be rotated in the direction of the blunt edge, undesired chopping of the food or food ingredients is avoided. Furthermore, this contributes to the safety of the mixing device. The mixing tool has an opposite sharp edge, so that the container with the mixing tool can also be used in a food processor. With a food processor that can rotate the mixing tool in opposite directions, the raw material of the food can be chopped.

The electric drive may be connected to the mixing tool by a releasable coupling. The coupling element of the releasable coupling may be coupled to the shaft of the driver. The coupling element of the releasable coupling may be coupled to the shaft of the mixing tool. The releasable coupling is located below the bottom of the container when the container is inserted into the recess of the bracket member. In this embodiment, the container can be easily detached from the holder part. In such an embodiment, the container can be handled particularly easily with the aid of the holder part and with the aid of a suitably configured food processor. Then, the coupling element coupled to the shaft of the mixing tool is located below the bottom of the container.

Preferably, the coupling elements of the housing parts of the mixing device are different from the coupling elements of the housing parts of the food processor. However, both coupling elements make it possible to connect them to the coupling elements of the container in such a way that a rotational movement can be transmitted from the coupling elements of the respective carrier part to the mixing tool (mixing tool). The coupling elements at the carrier part of the mixing device differ from the coupling elements at the carrier part of the food processor, so that the coupling elements at the carrier part of the mixing device can also be inserted differently. The difference is such that only the coupling element of the food processor can be constructed such that it can transmit very high torques. Thus, the coupling elements at the carrier part of the food processor are optimized for the transmission of high torques. The coupling elements of the carrier parts of the mixing device are optimized for various applications.

Preferably, the releasable coupling may be released by linear movement parallel to the motor shaft. The container can then advantageously be released from the holder part of the mixing device by lifting the container, i.e. away from the holder part of the mixing device upwards.

Preferably, the weight of the bracket member is at least 1.5kg, preferably at least 2kg, so that it can be sufficiently stable. The weight of the bracket member is preferably not more than 3kg so that the weight is not unnecessarily high. Ideally, the weight of the bracket member is between 2kg and 2.5 kg. The food processor may have a much higher weight of the bracket member. The weight of the housing part of the food processor may be at least twice or even at least three times the weight of the housing part of the mixing device, so that the food processor is stable even at very high rotational speeds. The weight of the frame part of the food processor may be more than 3kg, preferably more than 4 kg. In order to avoid unnecessarily high weights, the weight of the frame part of the food processor is preferably not more than 10kg, particularly preferably not more than 8 kg.

The holder part of the mixing device may have electrical contacts for heating the container, which are connected to electrical contacts on the bottom side of the container when the container is inserted into the recess. The holder part of the mixing device may comprise a controller by means of which the temperature for heating the container can be set. Preferably, the temperature that can be set is limited to 150 ℃, more preferably 125 ℃ for safety reasons. Preferably, the temperature that can be set by the holder part of the mixing device is lower than in the case of a food processor. This embodiment is also based on the idea that a particularly high temperature is only required for the preparation of several foods, so that it is not necessary to reach very high temperatures with a mixing device. Thus, the maximum temperature in the case of the mixing device may be limited to 125 ℃ and the maximum temperature in the case of the food processor may be limited to 160 ℃.

The holder part of the mixing device may comprise a rotatable knob for setting the temperature. Preferably, the housing part of the food processor further comprises a rotatable knob for setting the temperature. This avoids switching difficulties when removing the container from the food processor and inserting the holder part of the mixing device and vice versa.

The carrier part of the mixing device may comprise a rotatable knob for setting the rotational speed. Preferably, the housing part of the food processor further comprises a rotatable knob for setting the rotational speed. This avoids switching difficulties when the container is removed from the food processor and inserted into the holder part of the mixing device and vice versa.

The stand member of the mixing device may include a display for indicating the operating status. Preferably, the support member of the food processor further comprises a display for indicating the operational status. This avoids switching difficulties when the container is removed from the food processor and inserted into the holder part of the mixing device and vice versa.

If the housing parts of the food processor and the mixing device comprise rotatable buttons and a display for setting the temperature and/or for setting the rotational speed, the position of the rotatable buttons relative to the display is preferably the same for both housing parts. Thus, conversion difficulties can be avoided. For example, a rotatable knob may be arranged to the right of the display and adjacent to the display on both housing parts.

If the support element of the mixing device is constructed such that it can heat the container, the mixing device can also be used for other purposes, such as for cooking or boiling food or food ingredients, by means of the accessory. For example, a top container may be provided that can be placed on the container to enable steam cooking with the mixing device. For example, a cooking insert may be provided which may be suspended into the container to enable cooking.

The housing part of the mixing device and the housing part of the food processor preferably have a functionally equivalent or at least substantially functionally equivalent control for heating the container. This means that the food in the container can be heated at the same rate, regardless of whether the container is placed in the housing part of the mixing device or in the housing part of the food processor. For example, one liter of liquid is present in the container, the container is inserted into one of the above-mentioned holder parts, and the holder part has been set, for example, the liquid is heated to a temperature of at most 90 ℃. After setting, for example 300 seconds ± 10% (i.e. ± 30 seconds later), a temperature of 90 ℃ is reached in the container, whether or not the container has been inserted into the housing part of the mixing device or the housing part of the food processor. The heating profiles are then also identical or at least substantially identical. Thus, if a temperature of 50 ℃ is reached after 150 seconds ± 10%, this applies to the two mentioned stent components. Preferably, the heating curves differ by no more than ± 10%, further preferably by no more than ± 5%, particularly preferably by no more than ± 3%.

Detailed Description

Fig. 1 shows a mixing device with a holder part 1 and a container 2 (vessel). The bracket member 1 is disposed on the foundation 3. The holder part 1 has a recess 4 which can receive the lower part of the container 2. Thus, the container 2 can be inserted into the recess 4. The shape and diameter of the recess 4 are adapted to the shape and diameter of the lower part of the container 2 in order to be able to support the container 2 firmly and reliably by means of the holder part 1. As shown in fig. 1, the recess may be circular. The lower part of the container 2 is therefore also rounded in order to adapt the two shapes to each other. The outer diameter of the lower portion of the container 2 is slightly smaller than the inner diameter of the recess 4 so that the container 2 can be firmly supported by the holder part. However, other shapes may be provided. Preferably, the container 2 can be inserted in a rotationally fixed manner into the recess 4. The recess 4 and the lower part of the container 2 can thus be triangular, square, pentagonal or oval, so that the container 2 can be inserted in a rotationally fixed manner into the holder part.

The mixing tool 5, indicated by a dashed line, is located in the container 2, i.e. near the bottom of the container 2 and thus at the base of the container 2. The mixing tool 5 may be rotated by a shaft 6. The shaft 6 passes through the bottom of the container 2. The downwardly directed end of the shaft 6 comprises a connection 7.

The holder part 1 comprises an electric motor 8 with a shaft 9, indicated by a dashed line. The upwardly directed end of the shaft 9 comprises a coupling 10. The motor 8 is a hybrid stepper motor.

When the container 2 is inserted into the recess 4, the two coupling members 7 and 10 are thus connected to each other. If the shaft 9 of the motor 8 is rotated, the rotational movement is transferred from the shaft 9 to the shaft 6. Thus causing the mixing tool 5 to rotate. A gearbox is not necessary, since even without a gearbox the appropriate speed can be set by means of the hybrid stepper motor.

Fig. 2 shows an example of a mixing tool 5 having a blunt edge 11 and an opposite sharp edge 12. If the mixing tool 5 is rotated counter-clockwise as indicated by the arrow, the mixing tool 5 is rotated in the direction of the blunt edge 11. The mixing device according to the invention is constructed in principle such that the mixing tool 5 can only be rotated in the direction of the blunt edge 11.

Fig. 3 shows an axial cross section of the hybrid stepper motor. Fig. 4 shows a cross section of the hybrid stepper motor of fig. 3. The hybrid stepping motor includes a stator 13 and a rotor 14. The main body 15 of the stator 13 is preferably made entirely of metal, so that the hybrid stepping motor has a high weight. The body 15 of the stator 13 may be composed of a plurality of metal plates, which are combined into a package. The metal plates may be joined to each other by rivets.

The body 15 comprises a plurality of segments 16. The segments 16 project inwardly from the annular shape of the body 15. As shown in fig. 3, the outer contour of the ring shape may be circular. For example, the outer contour of the ring shape may also be square. As shown in fig. 4, there may be four segments 16. However, for example, six or eight segments 16 may also be present. Each segment 16 has a plurality of teeth 17 at its inward end. As shown in fig. 3, each segment 16 may have three teeth 17. However, there may also be more or less than three teeth 17 per segment 16, for example two, four or five teeth 17. The segment with teeth consists of a magnetizable material. The magnetizable material may be a ferromagnetic material, e.g. mainly comprising iron. However, it may also be a paramagnetic material.

Coils

18, 19 are wound around each segment 16. To ensure that the windings of the

coils

18, 19 are electrically insulated from the body 15, an electrical insulator 20 may be provided, if desired, which electrically insulates the windings of the

coils

18, 19 from the body 15. At an appropriate time during operation, current flows through the coils 18 in the opposite direction to the current through the coils 19 to rotate the rotor. In fig. 3, the possible current flow directions are indicated by "·" and "X" of each

coil

18, 19.

The rotor 14 is located inside the annular shape of the stator 13. The rotor 14 comprises a first rotation body 20 equipped with first teeth 21 and a second rotation body 22 equipped with second teeth 23 (see fig. 4). The rotating

bodies

20, 22 may be made of a paramagnetic material. However, the rotating

bodies

20, 22 preferably use a ferromagnetic material. One or both of the

rotating bodies

20, 22 may be respectively composed of a plurality of metal plates. The metal plates of the rotating body may be connected to each other by means of grooves or screws, for example. Alternatively, one or both of the

rotating bodies

20, 22 may be made in one piece. As shown in fig. 3, the first tooth 21 is located between two second teeth 23, and vice versa. The

teeth

21, 23 of the rotor 14 abut the teeth 17 of the stator 13 in such a way that a narrow gap is maintained between them.

The

teeth

21, 23 of the rotor 14 are preferably curved outwardly on their upper side such that the upper side of the

teeth

21, 23 forms a ring shape when viewed from above, as shown in fig. 3. In a corresponding manner, the upper side of the teeth 17 of the stator is then preferably bent inwards. This allows a particularly narrow gap to be set between the teeth 17 of the stator 13 on the one hand and the

teeth

21, 23 of the rotor 14 on the other hand.

Fig. 4 illustrates that the north pole N of the permanent magnet 24 extends into the first rotating body 20 and the south pole S of the permanent magnet 24 extends into the second rotating body 22. Thus, the first tooth 21 acts as a magnetic north pole, and the second tooth 23 acts as a magnetic south pole. As shown in fig. 3, a first tooth 21 may be directly adjacent to a second tooth 23 when viewed in plan, and the next first tooth 21 may be directly adjacent to the second tooth 23 when viewed in plan, such that there is no gap between the first and

second teeth

21, 23.

Fig. 3 illustrates that the second tooth 23a has been moved to the aligned position shown by the detent force by the tooth 17a of the upper coil 18. Thus, the tooth 17a is just opposite the tooth 23 a. In addition, the first tooth 21a has been moved to the aligned position shown by the detent force by the tooth 17b of the lower coil 19. Then, the tooth 17b is just opposite to the tooth 21 b. For this purpose, a current flows through the lower coil 19 in the opposite direction to the current flowing through the upper coil 18. During this time, no current flows through the side coils 18 and 19.

When the rotor 14 has reached the position shown in fig. 3, the current flow through the upper coil 18 and the lower coil 19 is interrupted, and the current then flows again in the opposite direction through the side coils 18, 19. Since the laterally arranged teeth 17 of the stator 13 are arranged offset with respect to the laterally arranged

teeth

21 and 23 of the rotor 14, a magnetic resistance force acts on the rotor 14 so that it further rotates in the counterclockwise direction.

Fig. 4 shows that the shaft 25 of the hybrid stepper motor can pass through the permanent magnet 24 and the two

rotational bodies

20, 22. Fig. 4 shows an example of a magnetic flux path 26 that may occur during operation of a hybrid stepper motor. This exemplary path shows the magnetic flux penetrating the first tooth 21 and the second tooth 23. The magnetic flux passes through the first tooth 21 toward the outside of the first tooth 21. The magnetic flux passes through the second tooth 23 in the opposite direction, i.e., from the outside of the second tooth 23 toward the inside of the second tooth 23.

There is a controller, not shown, of the hybrid stepper motor that controls the current as described above.

According to fig. 4, there is only one permanent magnet 24. However, there may also be two or more permanent magnets extending into the rotating

bodies

20, 22.

In fig. 5, a preferred embodiment of the container 2 is shown. The container 2 has a handle 27 made of plastic and a lower lid 28 open to the bottom. The lower cover 28 is connected to a container (container)29 made of metal by a rotary closure. The lid 28 can be removed from the container 29 by turning it. If the cover 28 is detached from the container 29 by rotation, the mixing tool located in the container 29 is thereby also released and can be removed from the container 29. The cover 28 covers the electrical contacts 30. The electrical contacts 30 belong to a heating device which is present at the bottom of the container 29. Total height h of the container 2_GAnd may be 20 cm. The height of the container 29 may be 16 cm. The mixing tool is located at the bottom of the container 29. The height of 16cm is sufficient to prevent the material from being sprayed upwards from container 2 or container 29 when the mixing tool is rotated at a speed of no more than 300 revolutions per minute. Thus, mixing can be performed without a lid at this speed of rotation, and then the container 29 must be closed.

The container 29 is substantially circular in cross-section. The diameter increases from bottom to top. At the upper edge, diameter D_oIs 20 cm. The length L of the container 2 is 27cm, seen from above, due to the handle 27. Viewed from above, the maximum width D due to the diameter_oIs 20 cm. Therefore, the footprint of the associated mixing device is no longer than 27cm and no wider than 20 cm.

The container shown in fig. 5 may be a component of a mixing device according to the invention or of a food processor according to the invention. The footprint of the mixing device is then at most 27cm long and at most 20cm wide. The footprint of the food processor is significantly larger and may be, for example, up to 30cm long and up to 30cm wide.

If the container 2 is part of a food processor, the top height of the container 29 may be 30 cm. If the container 2 is part of a mixing device, the height of the upper edge of the container 29 is smaller and may be, for example, 27 cm. This may ensure that the centre of gravity of the mixing device is lower than the centre of gravity of the food processor, so that the mixing device may also be operated in a stable manner.

Fig. 6 shows a top view of a mixing device with a holder part 1 indicated by a dashed line and a container inserted into the holder part 1, which comprises the container 29 and the handle 27 shown in fig. 5. Fig. 6 illustrates that the length and width of the footprint of the stent component 1 is slightly less than the length L and diameter D_o. Thus, only slightly more space is required in the kitchen to place the mixing device than in the container shown in fig. 5. Since a plurality of containers is usually required for cooking anyway, this design does not cause any significant additional space problems in the kitchen.

Fig. 7 shows a side view of the mixing device of fig. 5. The handle 27 of the container 2 extends at its bottom side a short distance into a recess in the housing of the holder part 1. This supports a correct alignment of the container 2 inserted in the holder part 1 and contributes to a rotationally fixed connection between the holder part 1 and the container 2. The electrical contacts 30 (see fig. 5) on the underside of the receptacle 9 are then inserted into the electrical sockets of the bracket member 1. This also ensures that the container 2 is inserted into the holder part 1 in a rotationally fixed manner. The relevant heating means can then be supplied with power through the holder part 1, in order to be able to heat the container 29 even during mixing.

The control panel of the housing part 1 comprises a display 31 and a rotatable knob 32. By pressing the button 32, the operating state can be changed and then displayed on the display 31. By rotating the knob 32, the rpm for the mixing tool or the temperature for heating the container 29 can be set. The operation and arrangement of the controller corresponds to the operation and arrangement of the controller on the food processor, which facilitates the operation of both devices. The food processor then also has a display and a rotatable knob to set at least the rpm and temperature of the mixing tool.

A control panel having a display 31 and a rotatable knob 32 is located on the ramp-shaped portion of the bracket member 1, which makes the operation easy. The underside of the handle 27 forms an angle a of more than 60 with the ramp-shaped portion. This allows the control panel to remain easily accessible. In addition, the handle 27 can be grasped from the side of the control panel, which also facilitates the operation. Thus, when the container 2 is inserted into the holder part 1, the handle 27 and the control panel are on the same side for operational reasons.

Height H of the mixing device to the upper edge of the container 29_RBelow the level of the food processor to the top of the container 29. This provides an advantageous center of gravity for the mixing device, which facilitates trouble-free operation.

In order to be able to prepare a large number of different foods, it is preferred that there are various accessories for the receptacle 2, such as a cooking insert, a top receptacle (e.g. a

Container), a plug-in base of the top container, a mixing attachment. The cooking insert is a container with a screen-shaped wall, which can be inserted into the container 2 leaving a space between the bottom of the cooking insert and the mixing tool. Subsequently, in one configuration, the container 2 may be closed with a lid. The top container is a container that can be placed on top of the container 2. The top container may for example be placed on the lid of the container 2. The lid then comprises an opening through which steam can flow from the container 2 into the top container. Hot steam may enter the top container for cooking via the mesh structure at the bottom of the top container. The top container may be longer and/or wider than the largest diameter of the container 2. The top container may include a lid. The male base of the top container is the base that can be inserted into the top container so that the top container is divided into two distinct layers. The insert base may have a mesh structure that is permeable to vapor. The mixing attachment is an attachment to a mixing tool. Thus mixing can be performedThe accessory is placed on the mixing tool. If the mixing attachment is placed on the mixing tool, the mixing tool and the mixing attachment can be rotated together, for example to be able to whip cream.

Fig. 7 shows the container 2 projecting freely from the holder part 1. This means that, as can be seen in fig. 7, only the lower part of the container 2 extends into the recess 4. Otherwise the container 2 is not supported otherwise. This also contributes to a small installation space. Due to the low rpm, it can stand freely.

Fig. 8 shows a food processor 33 with a holder part 34. The footprint of the bracket member 33 is greater than the maximum length and width of the plug-in container 2 having the container 29 and handle 27. The housing parts include rotatable knobs 32 and a display 31 by which a food processor 33 can be operated. Lid 35 is placed on container (container)29 of container (vessel) 2. The food processor 33 comprises a claw 36 of an electric locking mechanism for locking the cover 35, which claw can lock the cover 35 by a rotational movement such that the cover 35 cannot be moved. The top receptacle 37 is placed on the lid 35. Steam may flow into the top container 37 through openings in the lid 35 and through the mesh structure in the bottom of the top container 37. To cook ingredients in the top container 37 using steam, the top container 37 may be closed by a lid.

Fig. 8 illustrates that the container 2 does not protrude freely from the holder part 34 of the food processor. This means that not only the lower part of the container 2 extends into the recess 4. The container 2 is additionally supported, in particular in the locked state of the lid 35. This also allows for very high rotational speeds.

Fig. 9 shows a top view into the recess 4 of the holder part of the mixing device. The coupling element 38 is located at the bottom of the recess 4. The coupling element is firmly connected to the shaft of the electric drive of the mixing device situated behind it. Thus, the electric drive may rotate the coupling element 38. The coupling element 38 has a recess with three lateral notches 39 and an annular groove 40 at the centre of the coupling element.

Inside the recess 4, at the bottom, there is a channel 41 through which the liquid can flow downwards out of the holder part of the mixing device. Behind the elastic membrane 42 there is an electrical contact in the form of a socket. Above the electrical contacts, there are slots 43 in the membrane 42 through which the electrical plugs of the container can be inserted for connection to the socket. There are a total of five electrical contacts for supplying current to the heating means of the container and to the sensor system in order to be able to control the heating of the container. By controlling the container, it can be brought to a desired temperature.

The shaft of the mixing tool has a coupling element, which however has six protrusions 44, as shown in dashed lines in fig. 9. The projections 44 extend in pairs into the recesses 39 when the container is inserted into the recess 4. Thus, a coupling element with six projections 44 can be inserted into a coupling element with three recesses 39 in such a way that the two coupling elements are connected to one another in a rotationally fixed manner. The rotational movement of the coupling element with the recess 39 then rotates the mixing tool. The number of recesses 39 may also be greater or fewer. Thus, the number of protrusions 44 on the coupling element of the mixing tool is then changed in such a way that the protrusions 44 may extend in pairs into the recesses 39. Since the maximum torque that can be transmitted by the mixing device is small, the number of recesses can be small compared to the number of protrusions. However, the smaller number of recesses advantageously increases the flexibility of interaction with other coupling elements in order to be able to use the carrier part of the mixing device in other ways.

The shaft of the mixing tool may extend into the slot 40 to facilitate centering.

When the coupling element of the mixing tool has six protrusions 44, the food processor 33 shown in fig. 8 comprises a coupling element with six recesses at the bottom of its recess 4. The number of recesses and protrusions may also be greater or fewer. When the container 2 is inserted into the recess 4 of the food processor, the protrusion 44 of the coupling element of the mixing tool extends into each recess at the coupling element of the food processor. This makes it possible to transmit particularly large torques to the mixing tool. In the case of a food processor, this may be necessary. Otherwise, in the case of the holder part 34 of the food processor 33, the bottom of the recess 4 may correspond to the bottom of the recess 4 shown in fig. 9.
